Reverse Osmosis Systems

All BRS RO/DI systems have been recently been updated to reflect the latest in reverse osmosis technology with updated filters, components and design updates. The redesign also makes system selection much easier. The new Value and new Universal systems are now both capable of treating for chloramines and chlorine.

Aquarium Reverse Osmosis Systems are an economical, convenient way to put consistently pure water into your reef aquarium without running to the store to buy RO or distilled water. Your reef tank will certainly benefit from the installation of RO/DI systems, carbon blockers, and sediment filters, to name a few. Tap water, even when treated, will still contain traces of impurities, microorganisms, disinfection byproducts, inorganic chemicals, organic chemicals, and radionuclides. Although it is safe for people to ingest, this may not always apply to other species; especially reef tank residents like corals, exotic fish, and other invertebrates. Risks that come with exposing your reef tank's inhabitants to untreated, unfiltered water can be easily prevented by installing the right reef aquarium filtration system.

Bulk Reef Supply builds numerous RO/DI system set ups in our Minnesota warehouse using over 60% American-made components. We feature American made DOW, MATRIKX, Purtrex filters and American made MUR-LOK dual EPDM O-ring fittings on all of our reverse osmosis units. These NSF certified fittings and filters cost us more than inexpensive imports, but set our units apart from the competition.

Our customer service representatives are available to help you choose the right reverse osmosis/deionization system for your needs and space.
